Generally safe for the hardware, but requires careful disabling of automatic updates to prevent patching the exploit.

Physical discs rot. Optical media has a lifespan of 20–50 years. Digital storefronts (like the PS Store for PS3/Vita) eventually shut down. For preservationists, ripping games to ISOs is an act of archiving—a digital Noah’s Ark for interactive art.

If you see a website promising a "one-click PS4 ISO downloader" for your standard console, be cautious
